# Shannon-for-Dummies
Educational application
Exploration from Claude's Shannon initial theory to its practical application to satellite communications.
The application is using PysimpleGUI / PySimpleGUIWeb and runs either in local windows or in web pages.
The Web version via localhost is fully functional although not as convenient as the windowed version (only 1 plot open).
The look of the web version differs significantly from the local version (PySimpleGUIWeb is still beta).
The Web version in remote does work for a single user (all users connected can send commands but see the same page).
This mode is experimental and doesn't behave as a web server : users are not managed, the app closes when the user closes the window ...
The value of the application is essentially in the background information accessed by clicking labels of all inputs / outputs.
A Knowledge DB is coupled to the application for collaborative contributions on the subject opening technical discussions. At this stage the DB is local.

'Advanced': 'The model assumes that the communication channel is \"AWGN\", just Adding White Gaussian Noise to '
'the signal. This noise is supposed to be random and white which means that noise at a given time is '
'independent of noise at any other time, this implies that the noise has a flat and infinite spectrum.'
'This noise is also supposed to be Gaussian which means that its probability density function follows a '
'Gaussian law, with a variance associated to the Noise\'s power.\n\n'
'Although these assumptions seem very strong, they are quite accurately matching the cases of interest. '
'Many impairments are actually non linear and/or non additive, but just combining equivalent C/N of all '
'impairments as if they were fully AWGN is in most of the cases very accurate.'
'The reason for that is that the sum of random variables of unknown laws always tend to Gaussian and that '
'in most systems, thermal noise is dominating, is actually white and gaussian and is whitening the rest.\n\n'
'The tool accepts lists of comma separated CNRs which will be combined in that way. \n\n'
'In satellite systems, the noise is mainly coming from the electronics of the radio front end, the ground '
'seen by the antenna, the stars and the atmospheric attenuator. In case of rain, the signal is punished twice '
': the attenuation makes it weaker and the rain attenuator generates noise added to the overall noise.\n\n'

'(billions of cycles per second).\n\nFor satellite downlink (satellite to terminal), frequency bands '
'and frequencies are typically : L : 1.5 GHz , S : 2.2 GHz , C : 4 GHz , Ku : 12 GHz, Ka : 19 GHz, '
'Q : 40 GHz',
'-iSatAlt-':'Satellite Altitude [km]\n\nThe position of the satellite is expressed in latitude, longitude, '
'altitude. The program doesnt simulate the orbit, any satellite coordinates can be used. '
'A GEO satellite has a latitude of zero degrees and an altitude of 35786 km. LEO satellites '
'have an altitude lower than 2000 km. MEO\'s altitudes are between LEO and GEO : the O3B '
'constellation\'s altitude is 8063 km',
'-iSatLatLong-':'Satellite Latitude and Longitude [\N{DEGREE SIGN}]\n\nThe position of the satellite is '
'expressed in latitude, longitude, altitude. The program doesnt simulate the orbit, any '
'satellite coordinates can be used. A GEO satellite has a latitude of zero degrees and an '
'altitude of 35786 km. LEO satellites have an altitude lower than 2000 km. MEO\'s altitudes are'
' between LEO and GEO : the O3B constellation\'s altitude is 8063 km',
'-iGSLatLong-':'Ground Station Latitude and Longitude [\N{DEGREE SIGN}]\n\nThe position of the ground station '
'is expressed in latitude, longitude (the ground station is assumed to be at the surface of '
'the earth).\n\nThe position of the ground station is affecting the link availability due to'
' the differences in weather statistics at different locations on earth (tropical regions have '
'very heavy rains attenuating dramatically signals at high frequencies). It is also impacting '
'the elevation angle at which the satellite is seen and thus the length of the path in the rain.'
'\n\nThe position of the ground station is also impacting the overall path length and thus the '
'path dispersion loss.\n\nUseful link to find coordinates of interest : '
'https://www.gps-coordinates.net',
'-iAvail-':'Desired Link Availability [%]\n\nThe link availability in percentage of the time is a key '
'performance indicator for satellite communications.\n\nIn this program the only cause of '
'unavailability modelled in a probabilistic way is the attenuation caused by the atmosphere. A high '
'desired link availability corresponds to a high signal attenuation : only rare and severe weather '
'events exceeding this attenuation can interrupt the link.\n\nFor example for an availability of'
'99.9%, the attenuation considered in the link sizing is only exceeded for 0.1% of the time.',
'-iPathLength-':'Path Length [km] @ Elevation [\N{DEGREE SIGN}]\n\nDistance in kilometers from the satellite '
'to the ground station and elevation angle at which the satellite is seen. The actual distance'
' depends on the satellite\'s altitude and on the relative positions of the satellite and the '
'ground station.\n\nThe minimum path length is the satellite altitude, achieved when the ground'
' station is under the satellite (elevation = 90\N{DEGREE SIGN}).\n\nA negative elevation '
'implies that the satellite is not visible (beyond the horizon).',
'-iAtmLoss-':'Overall Atmospheric Attenuation [dB]\n\nThe Atmosphere is affecting radio wave propagation '
'with a signal attenuation caused by rain precipitations and clouds, by scintillation and '
'multi path effects, by sand and dust storms and also by atmospheric gases. \n\n'
'Simply speaking, the attenuation is increasing with the rain intensity and with the signal '
'frequency. C band is almost unaffected, Ku band is significantly affected, Ka band is severely '
'affected, Q band is dramatically affected\n\nThe overall attenuation depends on the actual '
'geographical location and on actual weather events. By nature, it is is thus statistical '
'(considering the past) or probabilistic (considering the future).\n\nAll effects included, '
'here are typical attenuation figures exceeded for 0.1% of the time in Europe from the GEO orbit '
': Ku: 2.5 dB, Ka: 6.9 dB, 22 dB \n\n'
'The program uses ITU-Rpy, python implementation of the ITU-R P Recommendations: '
'https://itu-rpy.readthedocs.io/en/latest/index.html',
'-iHPA-':'HPA Power at operating point [W]\n\nPower of the High Power Amplifier used as a last stage of '
'amplification in the satellite payload.'
'The value in watts is the value at operating point and for the carrier of interest.\n\n'
'Some satellites operate their HPAs at saturation in single carrier mode (typical DTH case).'
'Other satellites operate in multicarrier mode and reduced power (3dB Output Back Off is typical '
'for satellites serving VSATs)',
'-iSBeam-':'Satellite Half Power Beam Diameter [\N{DEGREE SIGN}]\n\nBeam diameter expressed as an angle at '
'satellite level. The power radiated at the edge of this beam is half of the power radiated at '
'the peak of the beam (on-axis value).\n\n'
'The beam evaluated is a basic one with simple illumination of a parabolic reflector\n\n'
'Typical beam size : 0.4-1.4 degrees for GEO HTS satellites, 3..6 degrees for GEO DTH satellites.',
'-iGOff-': 'Gain Offset from Peak [dB]\n\nThis offset allows to simulate terminals which are not all at '
'the beam peak. A 3 dB value would simulate a worst case position in a 3dB beam, typical approach '
'used in DTH. In single feed per beam HTS, a 1 dB value would give a typical median performance.'
'If you know the EIRP you have, the best is to iterate this value to get this EIRP '
'(the process will allow you to get a feeling of the tradeoff power / footprint size / EIRP. ',
'-iLoss-':'Output Section Losses [dB]\n\nLoss of signal\'s power in the path connecting the HPA to the '
'antenna. This loss is associated with filters, waveguide sections, switches ...\n\n'
'Typical value : 2.5 dB for large classical satellites, 1 dB for active antennas with HPAs close to '
'the feeds. If the power value is given at antenna level, the value should just be set to zero.',
'-iSCIR-':'Satellite C/I [dB]\n\nEffect of signal impairments associated with satellite implementation,'
'expressed as a signal to impairment noise ratio to be combined with the intrinsic Signal to Noise '
'Ratio affecting the link. Typical impairments are : intermodulation in the HPA, filtering effects, '
'oscillator\'s phase noise ...\n\n'
'The tool supports comma separated lists of C/I or C/N values expressed in dB. In addition to '
'satellites impairments, one can use this feature to also simulate infrastructure C/N, uplink C/N, '
'uplink interferences ...',
'-iOPow-':'Output Power [W]\n\nThe output power in watts at antenna output is associated with the useful '
'signal carrying user\'s information. It is also common to express this value in dBs (dBs transform '
'multiplications in additions, easier for human computation. Nevertheless, reasoning in watts tells '
'more about the physics.',
'-iSGain-':'Satellite Antenna Gain \n\nAn antenna concentrating the signal in the direction of the users is '
'almost always required to compensate for the path loss associated with the distance from the '
'satellite to the terminal.\n\nThe antenna gain is the ratio between the signal radiated '
'on the axis of the antenna (direction of maximum radiation) and the signal radiated by an '
'antenna radiating equally in all directions (for the same input power).\n\n'
'Antenna gains are without units but can be expressed in dB for convenience : dBi = dB relative to'
' isotropic antenna (antenna radiating equally in all directions)',
'-iEIRP-':'Equivalent Isotropic Radiated Power\n\nThe product Power x Gain expressed in Watts is a convenient '
'characterisation of the satellite radiation capability. It does correspond to the power which would '
'be required for an isotropic antenna radiating in the same way in the direction of the antenna '
'considered.\n\nThere is no "power creation" of course : for the directive antenna, the integral of '
'the radiated signal over a sphere centered on the antenna is at best equal to the input power '
'(lossless antenna).\n\n'
'As the value in watts is usually pretty big, a value in dBW is more convenient '
'for practical human computations.',
'-iPLoss-':'Path Dispersion Loss\n\nAssuming communication in free space (thus also in the vacuum), '
'this figure characterises the effect'
' of the distance from the satellite to the terminal. It gives an attenuation equivalent to the '
'inverse ratio of the power reaching one square meter at the terminal side and the equivalent '
'isotropic radiated power at satellite level.\n\n'
'This simply equals the surface in square meters of a sphere with a radius equal to the path length.'
'This attenuation is pretty big and is thus more humanly manageable in dB m\N{SUPERSCRIPT TWO}.\n\n'
'As the the vacuum is lossless, this "attenuation" is simply associated with the fact that only '
'a marginal fraction of the power radiated is captured in one square meter at destination, '
'the rest is going somewhere else.',
'-iPFD-':'Power Flux Density\n\nSignal power per square meter at the terminal side. '
'The actual power captured by the terminal is given by this value multiplied by the effective surface '
'of the terminal\'s antenna.\n\nNote that if the surface of antenna is not perpendicular to the '
'propagation direction of the radio wave, the effective surface presented to the wave is reduced '
'and less power is captured.',
'-iCPE-':'Customer Antenna Size [m]\n\nSize of the terminal antenna. A basic parabolic antenna with state of '
'the art efficiency is assumed.\n\n'
'The main source of noise is in general the terminal\'s radio front end'
' attached to the antenna. A state of the art Noise Temperature of 80K is assumed for this front end.',
'-iCPE_T-':'Noise Temperature [K]\n\nTotal Receiver\'s Clear Sky Noise Temperature. It includes all noise '
'temperature\'s contributors : receiver, sky, ground seen by the antenna... Antenna catalogs often '
'provide this value, the proposed default of 120K is a reasonable typical value. The computation '
'under rain fade conditions assumes 40K is affected by rain attenuation and the rest is not. ',
'-iCGain-':'Customer Antenna Effective Area and G/T\n\nThe effective area in square meters is expressing the '
'capability of the terminal to capture the Power Flux Density '
'(the multiplication of both give the power captured). The effective area is typically 60% of the '
'physical surface of the antenna\'s aperture.'
'This capability can also be equivalently expressed as a gain as it\'s the case for the satellite '
'antenna.\n\nThe figure of merit of a receive antenna is best expressed as the G/T ratio, '
'ratio between antenna gain and the total Noise temperature in Kelvins. The noise is mainly coming '
'from the electronics of the radio front end, the ground seen by the antenna, the stars and the '
'atmospheric attenuator.\n\nIn case of rain, the signal is punished twice : the '
'attenuation makes it weaker and the rain attenuator generates noise added to the overall noise.\n\n'
'The noise power density N\N{SUBSCRIPT ZERO} is derived from the noise temperature with a very '
'simple formula : N\N{SUBSCRIPT ZERO}=kTB (k being the Boltzmann constant), '
'the G/T leads easily to the key overall link figure of merit C/N\N{SUBSCRIPT ZERO}.',
'-iRXPow-':'RX Power at Antenna Output\n\nPower at receiver\'s antenna output before amplification. '
'This power is extremely small and can only be exploited after strong amplification.\n\n'
'As the main source of noise is in general coming from this amplification, the first amplification '
'stage has to be a Low Noise Amplifier.\n\nThis power is "C" in the Shannon\'s equation.',
'-iN0-' : 'Noise Power Density Antenna Output\n\nNoise Spectral Power Density of the radio front end under '
'actual link conditions (in Watts per MHz). '
'This PSD is N\N{SUBSCRIPT ZERO} in the Shannon\'s equation',
'-iBRinf-':'Bit Rate at infinite Bandwidth\n\nBit Rate theoretically achievable when the signal occupies an '
'infinite Bandwidth, this value is a useful asymptotic limit. The corresponding value, deduced '
'from the Shannon\'s formula is given by 1.443 C/N\N{SUBSCRIPT ZERO}\n\nThis bit rate is an '
'asymptotic value and is thus never achieved in practice.',
'-iBRhalf-':'Bit Rate at Spectral Efficiency=1/2\n\nBit Rate theoretically achievable at a Spectral Efficiency '
'= 1/2. The corresponding value, deduced from the Shannon\'s formula is given by 1.207 '
'C/N\N{SUBSCRIPT ZERO}\n\nThis operating point is bandwidth intensive ( bandwidth = 2 x bit rate). '
'Practical systems allow this operating point ( DVB-S2\'s QPSK 1/4 )',
'-iBRUnit-':'Bit Rate at Spectral Efficiency=1\n\nBit Rate theoretically achievable at a Spectral Efficiency '
'= 1. The corresponding value, deduced from the Shannon\'s formula is given by '
'C/N\N{SUBSCRIPT ZERO}.\n\nThis data point has remarkable attributes : bandwidth = bit rate and '
'C/N = 1 (equivalent to 0 dB), which means Noise Power = Signal Power.',
'-iBRdouble-':'Bit Rate at Spectral Efficiency=2\n\nBit Rate theoretically achievable at a Spectral Efficiency '
'= 1. The corresponding value, deduced from the Shannon\'s formula is given by '
'0.667 C/N\N{SUBSCRIPT ZERO}.\n\nThis operating point is relatively bandwidth efficient '
'( bandwidth = 0.5 x bit rate) and is often considered as a typical setting.',
'-iBW-':'Available Bandwidth [MHz]\n\nBandwith occupied by the communication channel. This bandwidth is usually'
' a degree of freedom of the system design, eventually constrained by technological constraints and '
'various kind of frequency usage regulations. Interestingly this parameter is also often mentally '
'constrained by past usages which were driven by technological constraints at that time.',
'-iRO-':'Nyquist Filter Rolloff [%]\n\n'
'To pass a limited bandwidth channel symbol have to be mapped on pulses, "filtered" to limit the '
'Bandwidth occupied. Theoretically, filtering can be "brickwall", one symbol per second passing in '
'1 Hertz. Practically, an excess of bandwidth is required, also called "Roll-Off of the filter.\n\n'
'The filter used is designed to respect the symmetry condition expressed in the Nyquist Criterion '
'avoiding inter-symbol interferences. Such a filter is called a Nyquist Filter. '
'and the mimimum theoretical bandwidth (Roll-Off = zero) is called Nyquist Bandwidth.\n\n'
'The Roll-Off or Excess of Bandwidth is usually expressed as a percentage of the Nyquist Bandwidth.',
'-iCIR-':'Receiver\'s C/I [dB]\n\nEffect of signal impairment associated with terminal implementation, '
'expressed as a signal to noise ratio to be combined with the intrinsic Signal to Noise Ratio affecting'
' the link.\n\nImpairments are multiple : Phase Noise of the radio front end, Quantization Noise of the'
' receiver\'s Analog to Digital Conversion, effect of imperfect synchronisation ...\n\n'
'The tool supports comma separated lists of C/I or C/N values expressed in dB. In addition to the '
'overall receiver\'s impairments, one can use this feature to simulate more details : downlink '
'interferences, LNB\'s phase noise, impairment of signal distribution ...\n\nNote that signal '
'impairments associated with the satellite and the receiver are combined together with the link '
'noise to evaluate the practical bit rate.',
'-iPenalty-':'Implementation Penalty vs theory [dB]\n\nTurbo and Turbo-like Codes are known for getting '
'"almost Shannon" performances. There are however still some implementation taxes '
': codes always have a residual bit error rate, making it very low requires some CNR margin.\n\n'
'Other practical aspects also cost signal\'s energy like time and frequency synchronisation, '
'physical layer framing...\n\nDVB-S2x, using LDPC codes and modern modulation related features '
'is typically 1 dB away of the Shannon Limit in Quasi Error Free operation. Real systems also have'
' to take margins, considering a reasonable value of 0.5 dB, a total penalty of 1.5 dB can be '
'considered as typical.\n\n'
'Original Turbo codes designed with higher residual bit error rates can get much closer '
'to the Shannon Limit. ',
'-iOH-':'Higher Layers Overhead [%]\n\nThe practical usage of information bits is based on a breakdown '
'in multiple communications layers, all spending bits for the logistics of carrying user bits.'
'For example, the process of encapsulation of IP datagrams on a DVB-S2x physical layer using'
' the GSE standard costs a few percents of net bit rate, spent in framing structures, integrity '
'control bits ...\n\n'
'In a modern efficient satellite forward communication system the overhead to IP costs typically 5%',
'-iNBW-':'Nyquist Bandwidth\n\nThe modulated carrier is passing bits in groups mapped on modulation symbols.'
'Satellite modulation schemes typically map from 1 to 8 bits on each symbol passing though the channel.'
'The Bit Rate is directly linked to the symbol rate, the number of symbols per second passing '
'the channel ( BR = SR . Number of Bits per Symbol ).\n\n'
'To pass a bandwidth limited channel, symbols have to be mapped on pulses "filtered" to limit the '
